The Killers showed up on last night's season finale of 'The Voice' to perform their latest single, 'Here With Me.' The Las Vegas rockers teamed up with contestant Cassadee Pope for the song -- a pairing that may have been a lucky one for Pope, who ended up being crowned the overall winner of Season 3 of 'The Voice' later in the show.

The Killers were the only alt-rock act to actually appear on last night's show, but there were several other such songs performed during the broadcast. Season 3 singers Cody Belew, Dez Duron and Diego Val all teamed up to cover Fountains of Wayne's 'Stacy's Mom,' a hit for the Jersey pop-rockers off their 2003 album 'Welcome Interstate Managers.'

Imagine Dragons' 'It's Time' is shaping up to be one of the bigger crossover hits of 2012, and contestants Pope, De'Borah, Liz Davis and Melanie Martinez came together to deliver a rousing rendition of the tune that wowed the coaches and the audience alike.

And finally, at the end of the show, all four 'Voice' coaches -- Blake Shelton, Christina Aguilera, Cee Lo Green and Adam Levine -- got together for a touching performance of the Green Day ballad 'Good Riddance (Time of Your Life)' to close things out. It was an especially appropriate pick, given that Green Day frontman Billie Joe Armstrong was an adviser on the show earlier in the season, having taped his appearance before shipping off the rehab this fall.

'Good Riddance' is a modern classic, and their performance showed just how versatile of a tune it is -- it can mean so many things. This time around, it meant another 'Voice' season had come and gone, and that fans will have to wait awhile for Season 4 to arrive.
